How marketplace seller applications and verification usually work
Short answer
Most marketplace seller applications ask who you are, how your business is registered, where you ship from, how you will be paid and what you plan to sell, then verify those details before you can sell. Under the US INFORM Consumers Act, online marketplaces must also collect and verify bank, tax and contact details from high-volume sellers. Prepare your documents in advance and enter them only on the marketplace's own website.
The usual stages
Every marketplace runs its own process and changes it over time, so treat this as a typical outline and read the marketplace's own seller help pages for the current steps.
- Account creation with an email address and phone number.
- Business information: legal name, business type, registered address, contact details.
- Identity verification of the person applying, often with a government-issued photo ID and sometimes a live photo or video call.
- Tax information, such as an EIN, or an SSN for some sole proprietors.
- Payout account: a bank account in the business or owner's name.
- Catalog and category review: what you plan to sell, sometimes with extra approval for restricted categories.
- Decision, or a request for more information.
Prepare a marketplace seller application
- Confirm the business details match everywhere. Make sure your legal business name, address and tax ID are written the same way on your registration, tax and bank records.
- Gather documents. Have your business registration, tax ID, a government-issued photo ID for the person applying, and a recent statement for the payout bank account ready.
- Prepare product information. List the categories and example products you plan to sell, with photos, prices and where the inventory is stored.
- Apply on the marketplace's own website. Start the application from the marketplace's own seller page, check the web address, and enter sensitive information only there.
- Respond to verification requests quickly. Answer any request for extra documents or a verification call promptly and with documents that match what you entered.
What US law requires marketplaces to collect
The INFORM Consumers Act requires online marketplaces to collect and verify certain information from "high-volume third-party sellers". According to the Federal Trade Commission, a seller qualifies if, in any continuous 12-month period during the previous 24 months, it made 200 or more separate sales of new or unused consumer products and $5,000 or more in gross revenue through that marketplace.
For those sellers, the FTC says marketplaces must collect a bank account, a tax identification number and contact information, and verify it. That is one reason marketplaces ask for these details and documents, and why the names on them need to match.
What to prepare before you start
- Business registration documents (LLC, corporation or sole proprietorship records).
- Your EIN or other tax ID.
- A government-issued photo ID for the person applying.
- A bank account in the business or owner's name, with a recent statement.
- A utility bill or statement showing the business address, if asked.
- Your store website, product photos, prices and the address where inventory is stored.
- A phone you can receive verification codes on.
The single most useful step is consistency: write your business name and address exactly the same way on every document and form.
Why applications get delayed
- Names or addresses that differ between the ID, bank statement and form.
- Blurry or cropped document photos.
- A website that is down, empty or does not match what you said you sell.
- Products in restricted categories without the required approvals.
- Missing a request for more information sent by email.
Stay safe while applying
Enter IDs, bank details and passwords only on the marketplace's own website after checking the address bar. No legitimate helper needs your seller login. Seller Channel never asks for IDs, bank details, passwords or seller logins: we only tell you whether your store looks like a fit and send the registration route, and you apply directly with the marketplace.
How long it takes
Timelines vary by marketplace, by category and by how complete your information is. Some applications are decided quickly, others take longer when documents need a second look. The marketplace's own help pages are the best guide to its current timing.
INFORM Consumers Act verification FAQs: what do marketplaces need to verify?
Online marketplaces must collect and verify a bank account, a tax ID and contact information from high-volume third-party sellers: those with 200 or more sales and $5,000 or more in gross revenue in a continuous 12-month period within the last 24 months. For a business, contact details include an ID for the person acting for it or a government record showing the business name and address.
The FTC says marketplaces must verify the information within 10 days and sellers must certify it at least once a year.
